That's fantastic news! :) Just curious... when
statements linking to other
properties has been implemented, will that include the ability to start defining
a class tree for the properties? It would be amazing if you could one day run
queries like "all items with any subclass of location set to Berlin", getting
all people born in there, items located there etc with a single simple instruction.
You can define such "sub-property" relationships, yes (but please don't
use
"subclass" for this, properties are not classes).
However, using such relationships for queries is a lot harder. They essentially
add an entire dimension of data to process. It's possible, and would be cool,
but it's not easy, so don't hold your breath...
